我需要用藍牙編寫某種客戶端 - 服務器應用程序。我需要在我的筆記本電腦上創建一些服務器（我使用java和bluecove），這將嚮應用程序發送一些數據（在android上）。這裏是我的代碼：android和bluecove
服務器：
public class OBEXPutServer {
static final String serverUUID = "11111111111111111111111111111123";
public static void main(String[] args) throws IOException {
LocalDevice.getLocalDevice().setDiscoverable(DiscoveryAgent.GIAC);
SessionNotifier serverConnection = (SessionNotifier) Connector.open("btgoep://localhost:"
+ serverUUID + ";name=ObexExample");
int count = 0;
while(count < 2) {
RequestHandler handler = new RequestHandler();
serverConnection.acceptAndOpen(handler);
System.out.println("Received OBEX connection " + (++count));
}
}
private static class RequestHandler extends ServerRequestHandler {
public int onPut(Operation op) {
try {
HeaderSet hs = op.getReceivedHeaders();
String name = (String) hs.getHeader(HeaderSet.NAME);
if (name != null) {
System.out.println("put name:" + name);
}
return ResponseCodes.OBEX_HTTP_OK;
} catch (IOException e) {
e.printStackTrace();
return ResponseCodes.OBEX_HTTP_UNAVAILABLE;
}
}
}
}
應用：
public class BTTestActivity extends Activity {
String dStarted = BluetoothAdapter.ACTION_DISCOVERY_STARTED;
String dFinished = BluetoothAdapter.ACTION_DISCOVERY_FINISHED;
BluetoothAdapter bluetooth = BluetoothAdapter.getDefaultAdapter();
static final String serverUUID = "11111111111111111111111111111123";
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
BroadcastReceiver discoveryResult = new BroadcastReceiver()
{
public void onReceive(Context context, Intent intent)
{
String remoteDeviceName = intent.getStringExtra(BluetoothDevice.EXTRA_NAME);
BluetoothDevice remoteDevice;
remoteDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
Log.i("@#$%^&*(*&^%$#@#$%^&*(", "WYSWIETLAM");
Toast.makeText(getApplicationContext(), "Discovered: " + remoteDeviceName + " address " + remoteDevice.getAddress(), Toast.LENGTH_SHORT).show();
try{
BluetoothDevice device = bluetooth.getRemoteDevice(remoteDevice.getAddress());
BluetoothSocket clientSocket = device.createRfcommSocketToServiceRecord(UUID.fromString(serverUUID));
clientSocket.connect();
} catch (IOException e) {
Log.d("BLUETOOTH", e.getMessage());
}
}
};
registerReceiver(discoveryResult, new IntentFilter(BluetoothDevice.ACTION_FOUND));
}
public void fun(View view)
{
bluetooth.enable();
if (!bluetooth.isDiscovering())
bluetooth.startDiscovery();
}
}
我的問題是，當我嘗試連接到從應用服務我得到這樣的事情：

有人知道這段代碼有什麼問題嗎？謝謝你的幫助。
編輯：
我會運行這個例子告訴你，我和我運行它，但它不是工作:(我有問題wyth服務器什麼他是「的StreamConnection的StreamConnection = connectionNotifier.acceptAndOpen停止（） ;」在啓動方法線和野兔日誌從您的Android應用：

在你的應用程序代碼中，我改變藍牙地址到筆記本電腦上的藍牙設備。你知道什麼是錯的，也許我需要用你的代碼做別的事情？我有一個問題。你在哪裏的應用程序代碼你設置服務器的UUID？
我注意到，即使我不運行服務器，來自你的應用程序的日誌也是一樣的。它看起來像應用程序看到我的筆記本電腦上只有藍牙適配器，並沒有看到我的筆記本電腦上運行的服務器應用程序。
順便說一句。我使用BlueSoleil 6.4.149.0作爲藍牙堆棧，我的「東芝for windows」堆棧不適用於bluecove。也許這是問題？
我在文章中做了一些修改，你能看看這個嗎？ – klemens
